In chick brooders using an oil burner, it has been the practice to provide a central heating drum having. an oil burner in the bottom thereof with which a feed pipe and an overflow pipe communicate. The drum is supported above the floor by suitable legs and is surrounded by an outwardly and downwardly extending canopy under which the chicks may assemble for warmth.

It is the object of this invention to provide a brooder of simplified construction but of greater efliciency both as to heating qualities and heat control, as well as assembly.

One feature of the invention resides in the burner mounted in the drum, and particularly the employment of a heat deflector and drip pan below the bottom of the drum and burner. It has been found desirable to interpose a shield or deflector between the bottom of the heater and the floor upon which the chicks are brooded to protect the floor and chicks from excess heat. It is also found desirable to provide a construction whereby ready access is bad to the inlet and outlet oil passages connected to the burner mounted in the bottom of the heating drum and to so arrange the oil inlet pipe that it may be shielded against the intense heat thrown off by the bottom of the heater drum. This construction, therefore,-providesfor positioning the oil inlet pipe below the shield or deflector in a position directly under the burner before directing it'upward to the burner inlet. It is also found desirable to perfect a construction wherein any oil overflow from the burner may be harmlessly led away. This is accomplished by utilizing the 0 shield or deflector as a drip pan to receive any overflow of oil from the burner and direct it into a cup mounted below the shield. In providing for the above construction and the ensuing advantages, the burner is formed with nipples suitably arranged below the shield so that the inlet and outlet pipes may be conveniently connected and disconnected therewith.

Other objects and features of the invention will be understood from the accompanying drawing and the following description and claims:

Fig. 1 is a central vertical section through the brooder with parts thereof shown in elevation. Fig. 2 is a section takenon the line 2-2 of Fig. 1.

Fig. 3 is a section taken on the line Fig. 1.

In the drawing, there is illustrated a brooder-- having an annular drum heater provided withperipheral side walls IE3, at bottom H and a top M. The heating drum is supported above the floor by legs l3 and is surrounded by a down-- wardly and outwardlyextending canopy M. The

canopy is supported by an annular ring [5 which is apertured at It to receive a hinge member ll. Thus the canopy may be swung about the hinge member ll to a raised position for inspecti0n,.

cleaning, etc.

At what may be termed the rear of the T drum, and positioned adjacent the hinged memwhich the usual flue I9 is attached.

20 which is formed with a central opening, and

a plurality of apertures 21 formed about the outer edge adjacent the wall of the heating drum. Said apertures are particularly positioned to control and direct the passage of heated gases from:-

the burner to the flue. For this purpose, the

apertures 2| are particularly spaced about the.-

baffle with respect to the flue. v

In order to prevent the heated gases from passing directly upward fromthe burner to the top of the drum and out the flue, and to provide an insulating dead air space centrally of the drum and cause the gases to travel onlythrough the apertures particularly positioned for that. purpose in the baffle, there is provided an inner drum. Said inner drum has a bottom 22, a. peripheral wall 23 and, a top 24. It is adapted to be positioned within the heating drumand re,- movable therefrom by mounting within the opening left in the top 12 of the drum and the opening in the baffle 20. Said inner drum is provided with central openings in both the bottom and top, but the wall 23 thereof entirely closes off any passageway to the flue I9 otherthan through the apertures 2| in the baffle. The central opening is provided in the inner drum to permit removal therethrough of the flame spreader 25 by means of a cleaner rod 26 and cleaner pipe 21.

A top lid 28 is mounted upon the cleaner rod for closing the central opening in the top 24 of the inner drum. Thus, the heating drum is covered by its immovable top l2, the top 24 of the inner drum and the lid 28. By reason of the inner air space since the heated gases passing through the central opening therein are trapped within the walls 22, 23, 24 and 28, and, while some heat 1 is lost due to conduction, no appreciable flow of heated gases occurs. Consequently, the entrapped gases in the inner drum will servesome- What as an insulating medium to prevent convection of excessive heat from the top of the heating drum.

The burner body comprises a casting secured to and supported upon the bottom I l of the heat-, ing drum. Said casting comprises an outer ring which supports an inner annular oil cup-3i by spaced ribs 32. A burner ring 33 is seated within the annular oil cup 3| above which the flame spreader 25 is positioned. On one side of the oil cup there is cast therewith a pipe coupling 34 to which there is connected an overflow cup 35 through a short pipe 36. The overflow cup has an offset enlargement which is connected with the overflow pipe 3?, the short pipe 38 being directly connected through the overflow cup, but not communicating therewith, with an inlet pipe 38. The burner above described is substantially shown and illustrated in Patent No. 1,982,363, issued November 27, 1934 on an application of Dewey I-I. Hill.

Supported by the legs i3 below the bottom 2 l of the burner drum, there is a combined heat deflector or shield and drip pan 39, said shield being spaced from the bottom it to provide an insulating dead air space therebetween and prevent the space below the burner under which the chicks 40 may huddle from being excessively heated by the bottom H of the burner drum. Substantially centrally of the shield but slightly off center, there is a concave portion is which serves as a drip pan and through the center of which the short pipe projects, said concave portion being so positioned with respect to the burner as to catch any overflow of oil therefrom and cause it to enter the overflow cup 35 so as to escape through the overflow pipe 3?. By reason of this construction, the inlet pipe 38 may be conveniently connected to and disconnected from the overflow cup as well as from the overflow pipe, such connections and disconnections being made below the burner drum and shield 39. This arrangement is most desirable for convenience in connecting and disconnecting the brooder from the oil pipe connections.

In order that the desired temperature may be maintained within the brooder canopy, the oil 60 inlet pipe 38 is caused to extend upwardly through an aperture 4! in that side of the canopy opposite the flue. Secured on the inner side of'the upstanding portion of the inlet pipe there is provided a bracket '32 supporting thermostatic wafer 33, the bracket and wafer extending well within the outer periphery of the canopy. Mounted upon the upper end of the pipe and exteriorly of the canopy there is a control valve mechanism comprising a sight feed 34, a shut-off valve and a thermostatically operated valve rod it, the rod it being actuated by a thermostatic control lever-.6? which is in turn actuated by the thermostatically actuated rod 38. said rod being adjustable with respect to the lever 47 by means of the screw threads and thumb nut 49. The valve lever is shielded by a cover and its control is limited by maximum and minimum set screws 55. Through this means, the temperature of the air within the canopy may be automatically controlled through a thermostatically controlled oil valve conveniently positioned exteriorly of the canopy. Such adjustments and observations may be made at a convenient outside position for control of the heat interiorly of the canopy.

The invention claimed is:

1. An oil burning heating drum for brooders including an oil burner mounted centrally of the bottom of the drum, a shield below said bottom supported in spaced relation thereto and extendingthroughout substantially the entire area thereof for insulating the air therebelow from said bottom, said shield having anapertured depression formed therein immediately below said burner for receiving oil overflow therefrom, and an oil overflow cup depending from said burner about aperture for receiving oil from the depression in the shield for discharge from the heating drum.

2.
